1 darkplaces/Xonotic on Linux uses system libraries. For Windows and macOS external dlls and dylibs are needed. Those reside in xonotic/misc/buildfiles
3 Because at the time of writing there is no automatism to build or update the games dependencies for those 2 platforms and the current dlls/dylibs are VERY outdated and thus also contain vulnerabilities, this page should document on where to obtain or how to build them, retaining API compatibility to darkplaces and also older OS platform versions like Windows XP.
5 For Windows, all libraries can/should be obtained from https://packages.msys2.org/ [1] with the exception of an official DLL release from the upstream being available (this is the case for jpeg-turbo and freetype) or if it has to be compiled on under Windows for some reason (eg. libcurl for Schannel (Windows crypto for HTTPS) support).
7 A handy tool to check dll deps on Windows is https://github.com/lucasg/Dependencies
12 libcurl is used for downloading *.pk3 files from servers

171 Is not loaded under Windows and crashes the game if it is and a map is loaded up.
172 Also it is not statically linked and thus requires libstdc++-6.dll and libgcc_s_sjlj-1.dll.
176 `./configure --enable-static --disable-shared --with-libccd=internal --enable-double-precision --prefix=$HOME/Games/xonotic/misc/builddeps/linux64/ode --with-pic`
179 *Note:* Old and not used in Xonotic but also not disabled :) Adding this for the sake of completeness.
